摘要

Device and process for navigation by integrating several inertial navigation systems hybrids.The present invention relates to a navigation device for a hybrid vehicle comprising at least one auxiliary sensor able to emit at least one auxiliary signal representative of a parameter and a plurality of hybrid navigation systems.Each hybrid navigation system comprising at least one inertial navigation system and at least a computer configured to hybridise to at least a signal representative of a medication inertial the at least one auxiliary signal, to form a hybrid signal SA u00edda each hybrid navigation system.According to the invention, this navigation device comprises a hybrid module of detection of smooth operation and weighting of these hybrid navigation systems.This module is configured to receive, on the one hand, the said at least one auxiliary signal and on the other hand, the signs hybrids of each hybrid navigation system and deduce at least one indicator of good functioning and a weighting for each system. Hybrid navigation and calculate a weighted signal hybrid those signs hybrids and coefiAware of the weighting respective hybrid navigation system
